Wisconsin was a U.S. state located in the north-central United States and is part of the Midwest and Great Lakes regions. It was bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, and Lake Superior to the north. Wisconsin's capital was Madison and its largest city was Milwaukee. The state comprised of 72 counties.
It was mentioned that it was the former home of Jackson's neighbour Merrill and his wife. Merril's wife assured him that she told him of moving to LA was a bad idea, due to witnessing a small crack caused by a small earthquake, and had to move back to Wisconsin, but Merril didn't take it seriously.
During the 2012 Apocalypse, Wisconsin was hit by massive earthquakes, killing numerous people living in the state. Later, on board Air Force One, as shown on the radar map of the world, the South Pole (though Anheuser mistakes it for being The North Pole) is now located somewhere in Wisconsin after the Earth's crust shifted at almost 23 degrees to the South West and the reversal of the magnetic poles. The ruins of Wisconsin were swept by a mega-tsunami when the Worldwide Flooding occurred.
After the apocalypse ended, Wisconsin is submerged underwater, but is left with extreme damage and is rendered uninhabitable.
